Good Morning America recently had 5 healthy ways to spice up kids' lunch boxes.  I made the corn muffins for my 3-year-old and he loves them.  They have bits of broccoli, corn, ham, and cheese.  The great thing about those is you can make a batch and freeze them, making morning lunch-making a breeze.  I also tried a version of the turkey roll-ups.

Note: The first recipe is made with peanut butter. My son's preschool doesn't allow peanut-butter, for good reason, so I just skipped over that one.
